When some architects set out to design a new building, they’re less concerned with functionality and more interested in creating a massive piece of art. Sometimes, those developers won’t let a pesky thing like gravity get in the way of their conceptual vision. If the laws of physics had any say in the matter, these buildings probably wouldn’t exist. But why let physics get in the way?

The bizarre shape of the Amsterdam’s WoZoCo Apartments is the result of a client’s desire to create a building that housed 100 units while providing good lighting and a spacious green common area. In order to save land in an already tightly packed city, thirteen units jut out of the front of the building.

The German couple that built this house titled “The World Stands on its Head” on an island in the Baltic Sea did it on a whim. They didn’t have any kind of grand statement in mind when they built the house and furnished it with upside down furniture, rendering it almost entirely uninhabitable.

Merely looking at Rotterdam’s Kubuswoningen, or “cube houses” is enough to cause vertigo.

The Balancing Barn in Suffolk, England, looks like it could tip over at any minute. Standing under the severe overhang must cause a profound sense of unease, but that didn’t stop the owner from hanging a swing off of it.

It’s unknown if any University of Cincinnati architecture students decided to switch out of the late professor Terry Brown’s classes after seeing that one of the homes he designed for himself was a massive mushroom supported by just a small stem. Or maybe this feat was why students wanted to study under him in the first place.

The Free Spirit Houses found in British Columbia, Canada, are perfect for adults who spent their childhoods wishing they could permanently move into their tree houses. These spheres are designed to be hung off of a tree or the edge of the cliff and tend to sway and rock with each heavy wind. Good luck getting a maintenance man to come up and work in there.
